The New York Mets received good medical news about left fielder Jason Bay and backup catcher Ronny Paulino on Thursday.

Bay hit off a tee at the team's facility in Port St. Lucie, Fla., and showed no sign of discomfort in his strained left side, The (Newark, N.J.) Star-Ledger reported. It is still uncertain when will Bay make his season debut.

Paulino was given the go-ahead to begin workouts. He was shut down last month after tests revealed irregularities in blood work, The Star-Ledger reported. Paulino is eligible to return from a drug suspension on Sunday, but he is a candidate for the disabled list because of his recent inactivity.
